Abstract
A fabrication method to prepare Pb(core)/ZnO(shell) nanostructures and its application for high-sensitivity nanothermometer, has demonstrated. The facile galvanic displacement method was used to prepare high sensitive solid-state Pb(core)/ZnO(shell) nanothermometers. The galvanic displacement method was used for its minimum equipment requirement, high throughput, and environmental friendly nature. The method also used Transmission electron microscopy (TEM) to determine the thermal expansion properties of solid Pb inside the nanocables in real time. Zn foil with Pb(NO 3 ) 2 solution was used to fabricate the Pb/ZnO nanocables at room temperature. The Pb/ZnO system can be suitable for nanothermometers for operating in the solid state. It was observed during the study that the ZnO and Pb chemical interactions can cause the cycling of temperature and thermometer degradation.
